Hard candy is made from an unusual combination of vinegar and sugar. It’s a great addition to a Christmas gift basket or cookie tin.
2 cups sugar
1/4 cup water
1/2 cup vinegar
2 tbsp butter
10 drops green food colouring
Place ingredients in a large saucepan and heat until sugar is dissolved in mixture. Boil until a candy thermometer indicates the hard ball stage for sugar is reached (266 degrees Fahrenheit). Be careful the sugar will be very hot and can burn easily.
Pour into a greased and lined 8 inch pan. Chill
Break into pieces and serve.
